TRANSMISSION MECHANISM.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed April is. 1906. Serial No. 311.5%.

T0 at whom, it may concern.-

Be it known that I, GEORGE S. CoMsTocK, a citizen of the United States,residing at Mechanicsburg, Cumberland county, State of Pennsylvania,have invented certain new and useful Improvements in TransmissionMechanism, of which the following is a specification.

This invention relates to improvements in mechanism is provided whichwill run.

smoothly without undue friction after the parts are worn out of true orif imperfectly fitted when constructed.

With this and other ends in view the invention consists in theconstruction and arrangement of parts hereinafter described and claimed.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a vertical section, with parts in side elevation, showing myinvention as applied to a double-piston reciprocating engine. Fig. 2 isa horizontal section through the device illustrated in Fig. 1 with partsin plan. Fig. 3 is a transverse section, and Fig. 4 is a plan and partsectional view, of a modification of a part of the invention.

Referring to the drawings, Figs. 1, 2, and 3, A A are the opposingcylinders of a two- I cylinder reciprocating, engine containing thepistonsB B, connected by a suitable yoke O. Extending transversely ofthe engine is the rotary shaft D, suitably journaled in theengine-casing, as illustrated in Figs. 2 and 3, having the crank portionE ournaled in the block F. Said block F is also provided with a verticaljournal-box adapted to receive a guide L, connected to the yoke O.

Referring to Fig. 4, the crank portion E of the shaft D is j ournaled ina block N, as above, and the block N is mounted to reciprocate in ahollow slotted guide M, the slots in said guide being sufficiently wideto permit a relative oscillatory movement in a horizontal-plane betweenthe guide and the sliding block N. d

In both of the above embodiments of the invention it will be seen that auniversal joint is established between the reciprocating and rotarymembers, the arrangement permitting a relative oscillatory movement onthe axis G G, the axis H H, and the axis of the crank E, and thus theparts readily adapt themselves to the easiest working positions in theoperation of the engine.

Obviously this invention is not limited to use in combination with anengine of the class above described, but is equally applicable to manyother machines, as pumps, aircompressors, steam-engines, &c.

I claim 1. The combination with a reciprocating piston and a rotarycrank-shaft, of a guide on said piston, and a block mounted toreciprocate on said guide and to oscillate in a transverse plane, saidblock also j'ournaled to the crank of said shaft.

2. The combination with a reciprocating piston and a rotary crank-shaft,of a yoke extending from said piston, a guide mounted in said yoke, anda block journaled to the crank of said shaft and connected to said guidefor relative reciprocatory and transverse oscillatory movement.

3. The combination with two opposed reciprocating members having thesame axis, of a yoke connecting said members, a guide mounted in saidyoke having a cylindrical bearing-surface, a block slidably connected tosaid guide, and a crank-shaft with which said block engages.
